3.4.5 Installation of Mains Shield for
Frequency Converters
This section is for the installation of a mains shield for the
frequency converter series with enclosure types D1, D2
and E1. It is not possible to install in the IP00/Chassis
versions as these have included as standard a metal cover.
These shields satisfy VBG-4 requirements.
Ordering numbers:
Enclosure types D1 and D2: 176F0799
Enclosure type E1: 176F1851

3.5 Enclsoure Type F Panel Options

3.5.1 Enclsoure Type F Options

Space Heaters and Thermostat
Mounted on the cabinet interior of enclosure type F
frequency converters, space heaters controlled via
automatic thermostat help control humidity inside the
enclosure, extending the lifetime of frequency converter
components in damp environments. The thermostat
default settings turn on the heaters at 10 °C (50 °F) and
turn them off at 15.6 °C (60 °F).
Cabinet Light with Power Outlet
A light mounted on the cabinet interior of enclosure type
F frequency converters increase visibility during servicing
and maintenance. The housing the light includes a power
outlet for temporarily powering tools or other devices,
available in two voltages:
•
230 V, 50 Hz, 2.5 A, CE/ENEC
•
120 V, 60 Hz, 5 A, UL/cUL
Transformer Tap Setup
If the cabinet light & outlet and/or the space heaters &
thermostat are installed Transformer T1 requires it taps to
be set to the proper input voltage. A 380-480/500 V
frequency converter is set initially to the 525 V tap and a
525-690 V frequency converter is set to the 690 V tap to
insure no overvoltage of secondary equipment occurs if
the tap is not changed before power is applied. See
Table 3.15 to set the proper tap at terminal T1 located in
the rectifier cabinet. For location in the frequency
converter, see Illustration 3.53.

NAMUR Terminals
NAMUR is an international association of automation
technology users in the process industries, primarily
chemical and pharmaceutical industries in Germany.
Selection of this option provides terminals organized and
labeled to the specifications of the NAMUR standard for
frequency converter input and output terminals. This
requires MCB 112 PTC Thermistor Card and MCB 113
Extended Relay Card.
RCD (Residual Current Device)
Uses the core balance method to monitor ground fault
currents in grounded and high-resistance grounded
systems (TN and TT systems in IEC terminology). There is a
pre-warning (50% of main alarm set-point) and a main
alarm set-point. Associated with each set-point is an SPDT
alarm relay for external use. Requires an external "window-
type" current transformer (supplied and installed by
customer).

Insulation Resistance Monitor (IRM)
Monitors the insulation resistance in ungrounded systems
(IT systems in IEC terminology) between the system phase
conductors and ground. There is an ohmic pre-warning
and a main alarm set-point for the insulation level.
Associated with each set-point is an SPDT alarm relay for
external use. Note: only one insulation resistance monitor
can be connected to each ungrounded (IT) system.
